“…A detailed review of this literature is beyond the scope of this paper. Briefly these articles can be categorized as: (a) arguments for the conduct of evaluation (e.g., Baker, 1977;Lombana, 1985); (b) how-to articles for a variety of evaluation methodologies (e.g., Cook, 1989, a primer on needs assessments; Miller & Warner, 1975, on conducting single subject research and evaluation); (c) approaches (e.g., Krumboltz, 1974); and (d) examples (e.g., Bruckner & Thompson, 1987). However, most examples are unconnected to evaluation needs in support of CDGC programs and, therefore, are of limited usefulness in this regard.…”
